+# Slingcode for YunoHost
+
+[](https://dash.yunohost.org/appci/app/slingcode)  
+[](https://install-app.yunohost.org/?app=slingcode)
+
+*[Lire ce readme en français.](./README_fr.md)*
+
+> *This package allow you to install Slingcode quickly and simply on a YunoHost server.
+If you don't have YunoHost, please see [here](https://yunohost.org/#/install) to know how to install and enjoy it.*
+
+## Overview
+
+Slingcode is a code editor contained in a single HTML file. Therefore, it has no server component, so all of your data is stored in your browser's cache. However, it is still possible to make web apps, run them, export them, and even share them using peer-to-peer.

+
+*[Read this Slingcode in english.](./README.md)*

+Si vous n’avez pas YunoHost, regardez [ici](https://yunohost.org/#/install) pour savoir comment l’installer et en profiter.*
+
+## Vue d’ensemble
+
+Slingcode est un éditeur de code contenu dans un unique fichier HTML. Il n'a pas de composant serveur, ce qui signifie que toutes vos données sont stockées dans le cache de votre navigateur. Cependant, il est toujours possible de créer des applications Web, de les exécuter, de les exporter et même de les partager en peer-to-peer.
